Question 52 pts
Results Section write up: Feedback level (positive versus negative) was used as the independent variable and self-intelligence ratings as the dependent variable. Results showed a significant difference between groups, t(38) = 3.45, p < .01. Participants rated their own intelligence higher in the positive feedback condition (M = 4.55, SD = 1.11) than participants in the negative feedback condition (M = 2.22, SD = .09). (fake results from fake date)
Using the write up of the results section from an APA empirical research article. Identify which test was conducted?
